Hello,
could you send me the current datasheets for MB90F897SPMCR-GSE1 and MB90F349CASPMC-GS-N2E1?
I can´t these on www.cypress.com
Thanks.
Best regards

Show LessCould you please send me the MB91F524FWCPMC-GSE1 programming spec?
Thank you so much.
Dear sir,
Please provide this data sheet.

Hello All,
I need to Erase and Write the SA0 Sector in MB95F778L, but i am not able write the data into that,can any one help me on this please.
below i mentioned my example code for erasing and writing the data.(This same code is working well for SA3 sector)
Note::
SSEN bit is enabled.
SWRE0 = 0x0F;
For Sector erasing::
{
__wait_nop();
__wait_nop();
FSR_WRE = 1;
__wait_nop();
__wait_nop();
SWRE0 |= DUALFLASH_APPL_WEN_MASK;
__DI();
*((uint8_t*)((SectorStartAddress & 0xF000) | 0x0AAA)) = 0xAA;
*((uint8_t*)((SectorStartAddress & 0xF000) | 0x0554)) = 0x55;
*((uint8_t*)((SectorStartAddress & 0xF000) | 0x0AAA)) = 0x80;
*((uint8_t*)((SectorStartAddress & 0xF000) | 0x0AAA)) = 0xAA;
*((uint8_t*)((SectorStartAddress & 0xF000) | 0x0554)) = 0x55;
*((uint8_t*)SectorStartAddress) = 0x30;
__wait_nop();
__wait_nop();
__EI();
}
For Sector Writting:
{
__DI();
FSR_WRE = 1;
__wait_nop();
__wait_nop();
SWRE0 |= DUALFLASH_APPL_WEN_MASK;
*((uint8_t*)((Address & 0xF000) | 0x0AAA)) = 0xAA;
*((uint8_t*)((Address & 0xF000) | 0x0554)) = 0x55;
*((uint8_t*)((Address & 0xF000) | 0x0AAA)) = 0xA0;
*((uint8_t*)(Address)) = u8Data;
__wait_nop();
__wait_nop();
while (!FSR_RDY);
__EI();
}
Thanks

Show LessHello All,
In the Core Test of the STL, the interrupt sub-test for confirms that the function of each stage works correctly in the attached block diagram. This message can learn form former Case #00396744.(Also can refer to the figure).
Recently, TÜV Rheinland have a question. Please we consider the bit error whether or not will cause the unexpected interrupt ?
So I want know if the result of the Core Test is good, that can prove that don't occur bit error or unexpected interrupt ?
Best regards.

お世話になっております。
現在、以下のUSB内蔵製品を検討しております。
- FM3 MB9B316R PMC-G-JNE2
- FM4 MB9B366R PMC-G-JNE2
・上記の内蔵USB経由で内蔵Flashのプログラミングは可能でしょうか?
(そのようなドライバは用意されておりますでしょうか?)
KIT上では、"FLASH USB Direct Programmer"を使用する場合には、USB-シリアル変換が外付けで必要になるようですが、
直接内蔵USBで書き込みができるか確認させてください。
エンドユーザがUSB経由でFM-MCUのFlashに書き込む使用方法を想定しています。
もし、対応できる場合は、やり方をご教示ください。
また、アプリケーションノートがありましたらご紹介ください。
宜しくお願い致します。

■質問
FMファミリのデータシートの注意事項には、C端子に関する注意事項として
『必ずC端子とGND端子の間に外付けでコンデンサを接続してください(容量は4.7pF推奨)』
と記載されています。
このコンデンサについて、容量以外に満たさなければならないスペックはありますか?
(コンデンサのスペックは、容量以外には耐圧や精度などがございますが、
それらは気にしなくても良いということでしょうか)
■補足
例えばS6E2Cxデータシートではp.67に、上記質問のC端子に関する
記載がございます。

The customer wants to use DMA transfer with these settings.
DMACB:
EM=1 (Dose not clear DMACA:EB bit (bit31) upon completion of the transfer.)
RC=1 (Enables the reload function of BC/TC.)
RS=1(Enables the reload function of the transfer source address.)
RD=0 (Enables the reload function of the transfer destination address.)
Can he set?
There is the description on the manual.
"This function can only be used for hardware transfer. To use the function, enable the reload function of RC, RS and
RD bits."
Is it a rule that must be obeyed?
Best regards,
Inoue
Show LessBy Interrupt of MFS, can be DMA transfer that is Hardware-Block transfer or Hardware-Burst transfer used?
If yes, How to use it?

Show LessI want to program the XC164-16 via another µC. I want to use the BSL/ASC protocol over UART. I found information in application notes that state that therefore a first and second stage bootloader must be programmed on the XC164-16 before the application data can be programmed. I also found out that memtool contains the mentioned first and second stage bootloader.
Is there any way to get the binaries/source code of the first and second stage bootloader used by memtools?
Best
